In its simplest form the speed trap measures how long it takes for an object to pass two sensors and calculates the speed it was travelling. The speed in cm/sec is shown on the LCD display and also on an indicator dial similar to an analog speedometer used on many cars where a pointer rotates to point to the speed.
